I have a RaQ4i.

Yesterday, my httpd processes were spinning out of control and eating up all cpu and ram. This would happen within minutes fo a reboot.

Eventually, I decided to get a few hours of sleep and come back. (No customers on this server, but I do have personal websites there.) Anyway, I expected no response from the server this morning. Instead, everything seems almost normal again.

I left my ssh client connected, and this command line error showed up:

xcalloc: allocation error, size = 476

Recent odd entries in my apache logs, with a few of each:

Ouch! malloc failed in malloc_block()

[warn] child process 621 still did not exit, sending a SIGTERM

[notice] caught SIGTERM, shutting down
[notice] Apache configured -- resuming normal operations

[error] (32)Broken pipe: accept: (client socket)

I had 28 Broken pipe errors within 10 seconds.

I'm not even sure where to begin. I have done some searches and have seen it suggested this could be related to php/MySQL.

Does anyone see anything familiar? Any suggestions?

Hello,

Have you got your raq box completely up to date?

Yep, all patches have been applied.... within the last 20 days, anyway. Unless I'm really worried, I usually let some of the more brave out there test them.

Also, I forgot to say... I did set max requests per child to 300, hoping it might help. I don't think it made a difference, since this box has crashed for no apparent reason before and then ran fine for awhile. Until now, I've just never seen what crashed it.
