LSWS Crashing (4.1.8 and 4.1.10)

[MikeDVB]

LSWS works fine for hours, days, or weeks and then it suddenly stops processing requests it seems. When I turned on full debug logging I see a TON of this right before it stops working:

PHP Code:

2012-01-21 17:00:49.174 [DEBUG] [MMAP] Release mapped data at 0x2aaaad197000
2012-01-21 17:00:49.174 [DEBUG] [MMAP] Release mapped data at 0x2aaaae1a0000
2012-01-21 17:00:49.174 [DEBUG] [MMAP] Release mapped data at 0x2aaaaad56000
2012-01-21 17:00:49.174 [DEBUG] [MMAP] Release mapped data at 0x2aaaaad54000 


It's done this 4 times today (but not once before today) - I'm not sure if this is perhaps a bad memory module in the server or some obscure bug in LiteSpeed we're hitting.

I've emailed bug@ but haven't gotten a response (not surprised, it's Saturday).

I see a lot of this in the stderr.log as well:

Not sure what to try at this point, hoping somebody from LSWS can chime in. In the interim I've written a script to check the number of LSPHP processes once per second, if it drops below 5 it will restart LiteSpeed and then wait 30 seconds before checking again. It's not ideal, but will avoid manual restarts until this is resolved.
