    Error: broken pipe!

    Hi, Recently there was an incident in our DC which caused our server to shutdown for a while. After recovering the server, we found that we now get heaps of errors in the LiteSpeed server logs: connection to [/tmp/lshttpd/lsphp5.sock.750] on request #1, confirmed, 1, associated process...

    [RESOLVED] APC not working correctly?

    We had the same problem where APC keeps crashing. We then reverted PHP LSAPI back from 5.3 to 5.2, everyting was smooth again. EDIT: Spoke too soon. Somehow we still get the same issue... :(

    503 error / connection reset by peers / Wordpress

    Looks like it's a PHP bug. I've compiled 5.2.11 and it's now working fine. Thanks George!

    503 error / connection reset by peers / Wordpress

    Thanks for the suggestion George. We've tried to increase the PHP memory size to almost 1GB, didn't help. The PHP version aren't the same. It's 5.2.5 on Apache vs 5.2.10 on LSWS, however, the configurations are exactly the same. I've compared phpinfo and made sure of it. We are using APC, but...

    503 error / connection reset by peers / Wordpress

    Hi, We are experiencing 503 errors on a particular Wordpress plugin (wpUserLinks). Every time a user submits a POST form, it responses 503. The following is the error log: 2009-10-08 21:40:05.961 [INFO] [xxx] connection to [/tmp/lshttpd/lsphp5.sock] on request #176, confirmed, 1, associated...

    cache function ?

    Hi, Does the VPS license have the cache feature enabled? We have a couple of VPS licenses installed and we cannot get any of them working. LSWS cache settings are set. Apache directives are set. The cache directory is still empty. How do we go about identifying the cause?

    Need some tips for tuning the web server

    Looks like there wasn't enough memory allocated to lsphp5, I didn't realise APC shm size is counted towards the memory limit. I have increased the memory limit now and hopefully this problem will go away. :-)

    Need some tips for tuning the web server

    Hi auser, thanks for the tips. We are actually working with the author of W3 Total Cache to solve some potential issues. Unfortunately we can't trace that pid because the server was completely dead and we had to switch it to rescue mode and bring it back. By then the process was no longer exist.

    Need some tips for tuning the web server

    Hi mistwang, I think I need some more help. Our server has just had a huge load spike, lsphp5 was taking up all the CPU, and made the server unresponsive, couldn't even ping or SSH into the server. The server log just before the huge spike (domains are masked): 2009-09-07 03:01:52.427...

    Need some tips for tuning the web server

    Thanks mistwang. I had looked into the possibility of a small scale DoS attack. But at the time of the high load (which sustained for about 10-15 minutes), requests per second was only about 50-60, which the server should have handled it without causing such a high load. There was no cron jobs...

    We have just experienced an unusual high load. There were lots of lsphp5 processes, I'm not sure how to tackle this issue, here's a snapshot of the processes:

    Need some tips for tuning the web server

    Thank you mistwang! I've unset max idle time and connection keepalive timeout and set the initial request timeout to 60 per your instruction. On a busy site though, wouldn't that cause unneccesarry overheads? i.e. too many idle/keep alive connections? It's interesting that you mentioned the two...

    Need some tips for tuning the web server

    I see, thanks guys. The reason for my post is that, the posted server load was taken during off peak time, and the current server only hosts a small portion of our sites. We are planning to migrate our larger sites to the same server in the upcoming weeks, and I was a bit worried that the...

    Need some tips for tuning the web server

    Hi guys, We are currently using LSWS to power a number of Wordpress installations on a 2GB VPS slice. The VPS slice is dedicated for serving LSWS requests (so MySQL is served remotely), LSWS is the latest (4.0.10 Enterprise), PHP is 5.2.10 with APC and Memcache enabled. The Wordpress...

    Cacti template import error?

    Hi Xing thank you for your reply. I *did* try 0.8.6h, and got the same errors, so I guess it could be some other problems?
