Hi all, Okay, the title isn't very descriptive, but I haven't much to work with :-/ We're having a recurrent problem with Apache 2.2 on two Solaris 9 boxes: it hangs, and becomes unresponsive. Connecting to the port 80, the connection is established, but stays stuck, and send no data at all. I think it started with version 2.2, though it's difficult to say when. When the problem occurs, a simple restart is enough to get it to work again (the children are killed, but the parent process is kept alive). the only messages I find in the log are about «deadlock situations» (see below), however, they happen quite a long time before the last working request is logged. In the exemple below, the last log before restart is at 14/Apr/2008:19:59:50 +0200. Nothing else there. I only found the following post which might relate to it, except in my case, Apache is built with the worker MPM, not prefork: http://www.mail-archive.com/dev@xxxxxxxxxxxxxxxx/msg39632.html Any idea? I'd like to keep the worker MPM if possible, AFAICT, it's more lightweight and more adequate to our use. TIA, Laurent [Fri Apr 11 18:53:07 2008] [emerg] (45)Deadlock situation detected/avoided: apr_proc_mutex_lock failed. Attempting to shutdown process gracefully.
