after upgrade, httpd_ls_bak error

[aww]

I've always had this httpd_ls_bak error after upgrades, seems minor but figure I better report it:

Would you like to restart it right now [Y/n]?

[OK] Lease License key #2 will expire in XX days!
/usr/local/apache/bin/httpd_ls_bak: invalid option -- k

The error message is mainly because some version of Apache support "-k" option, some version does not. We are aware of it and will address it later.

Thanks!

We got on one server similar problems. LSWS just stop working. Proces lshttpd hits CPU to 100% for couple of minutes. We tried to restart/stop/start lsws and is just ignoring.

After couple of starts working again.

This LSWS works before upgrade great without any downtimes. Now every day we suffer this strange bug/problem.

Any idea ?

P.S.
we are now swiching back to v3.3.14 to see if this happen again.

We have noticed the "failed to start listener on address *:7080" problem on one server, we will have it addressed in 3.3.16.

But the 100% cpu of lshttpd is something else, if you notice that again, please strace it, then "kill -USR2 <pid_of_100%_CPU_lshttpd>" to turn on debug logging, let it run for a little while, then kill it. send us the error log and strace log.

[iCARus]

This problem exist in v3.3.14 too.

But strange:

After lshttpd is on 100% CPU, is like this
2031 nobody 15 0 29612 23m 8880 S 100 0.6 0:01.41 lshttpd

If everything is ok then top shows(with slash and dot):

2031 nobody 15 0 29612 23m 8880 S 1 0.6 0:01.41 ./lshttpd

This is really annoying while every day we go downtime of couple of min.

[mistwang]

The problem is mainly caused by high I/O wait due to more than 20,000 core files under /usr/local/apache/htdoc/mrtg/ directory. After removing those core files, the server run pretty smooth.

If notice more problem just let me know.

[iCARus]

This problem still exist. We don't have anymore MRTG installed.
