http://issues.apache.org/bugzilla/show_bug.cgi?id=29277 Apache gets locked Summary: Apache gets locked Product: Apache httpd-2.0 Version: 2.0.49 Platform: Sun OS/Version: Solaris Status: UNCONFIRMED Severity: Normal Priority: Other Component: All AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I've recently upgraded my apache+ssl server from version 2.0.48 toapache+ssl 2.0.49 using mod_worker. I use Solaris Sparc as my operating system. After the upgrade my apache server became really unstable, sometimes it stops responding and only return after a restart. I did a truss atchild and parent process and I found this : Child Process... 17512: lwp_sema_wait(0xFD109E78) (sleeping...) 17512: lwp_sema_wait(0xFD007E78) (sleeping...) 17512: lwp_sema_wait(0xFDA03E78) (sleeping...) 17512: lwp_sema_wait(0xFBA0BE78) (sleeping...) 17512: lwp_sema_wait(0xFC407E78) (sleeping...) 17512: lwp_sema_wait(0xFC203E78) (sleeping...) 17512: lwp_sema_wait(0xFBC0FE78) (sleeping...) 17512: lwp_sema_wait(0xFCD01E78) (sleeping...) 17512: lwp_sema_wait(0xFC509E78) (sleeping...) 17512: lwp_sema_wait(0xFC101E78) (sleeping...) 17512: lwp_sema_wait(0xFD40FE78) (sleeping...) Parent Process... 17104: poll(0xFFBEF920, 0, 1000) = 0 17104: write(9, " !", 1) = 1 17104: waitid(P_ALL, 0, 0xFFBEF8D0, WEXITED|WTRAPPED|WSTOPPED|WNOHANG)= 0 17104: poll(0xFFBEF920, 0, 1000) = 0 17104: write(9, " !", 1) = 1 17104: waitid(P_ALL, 0, 0xFFBEF8D0, WEXITED|WTRAPPED|WSTOPPED|WNOHANG)= 0 It seems that all child process get locked, and the parent stay in loop waiting for a change at it's child status. My errorlog file shows a Segmentation Fault at a child process exactly at the moment of the "not responding" apache. [Fri May 21 14:41:03 2004] [notice] child pid 17483 exit signal Segmentation fault (11) Does anyone has a clue about it? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
