Bug #80804
Updated by Fedir RYKHTIK about 7 years ago
Hi there, We have a really strange problem with locks : sometimes, Apache is completely saturated, too much processes, looks like, because becasue of TYPO3 locking system. The bug appear really sometimes, but now more and more regularly, 1 time / day. Really annoying bug, it puts all sites on the server down. Actual solutions : or to remove all lock files from typo3temp, or to restart Apache. Here are some strace logs : # strace -p 5886 Process 5886 attached restart_syscall(<... resuming interrupted call ...>) = 0 open("/home/www/mysite.com/www/typo3temp/locks/flock_b3b32a2d422265cd25c3323ed0157f81", O_WRONLY|O_CREAT, 0666) = 5 fstat(5, {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 lseek(5, 0, SEEK_CUR) = 0 stat("/home/www/mysite.com/www/typo3temp/locks/flock_b3b32a2d422265cd25c3323ed0157f81", {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 chmod("/home/www/mysite.com/www/typo3temp/locks/flock_b3b32a2d422265cd25c3323ed0157f81", 0664) = -1 EPERM (Operation not permitted) flock(5, LOCK_EX) = 0 open("/home/www/mysite.com/www/typo3temp/locks/flock_7bfc94f72787757bc18f8d24791673b2", O_WRONLY|O_CREAT, 0666) = 134 fstat(134, {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 lseek(134, 0, SEEK_CUR) = 0 close(135) = 0 stat("/home/www/mysite.com/www/typo3temp/locks/flock_7bfc94f72787757bc18f8d24791673b2", {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 chmod("/home/www/mysite.com/www/typo3temp/locks/flock_7bfc94f72787757bc18f8d24791673b2", 0664) = 0 flock(134, LOCK_EX|LOCK_NB) = -1 EAGAIN (Resource temporarily unavailable) flock(5, LOCK_UN) = 0 close(5) = 0 nanosleep({0, 100000000}, NULL) = 0 open("/home/www/mysite.com/www/typo3temp/locks/flock_b3b32a2d422265cd25c3323ed0157f81", O_WRONLY|O_CREAT, 0666) = 5 fstat(5, {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 lseek(5, 0, SEEK_CUR) = 0 stat("/home/www/mysite.com/www/typo3temp/locks/flock_b3b32a2d422265cd25c3323ed0157f81", {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 chmod("/home/www/mysite.com/www/typo3temp/locks/flock_b3b32a2d422265cd25c3323ed0157f81", 0664) = -1 EPERM (Operation not permitted) flock(5, LOCK_EX) = 0 open("/home/www/mysite.com/www/typo3temp/locks/flock_7bfc94f72787757bc18f8d24791673b2", O_WRONLY|O_CREAT, 0666) = 135 fstat(135, {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 lseek(135, 0, SEEK_CUR) = 0 close(134) = 0 stat("/home/www/mysite.com/www/typo3temp/locks/flock_7bfc94f72787757bc18f8d24791673b2", {st_mode=S_IFREG|0664, st_size=0, ...}) = 0 chmod("/home/www/mysite.com/www/typo3temp/locks/flock_7bfc94f72787757bc18f8d24791673b2", 0664) = 0 flock(135, LOCK_EX|LOCK_NB) = -1 EAGAIN (Resource temporarily unavailable) flock(5, LOCK_UN) = 0 close(5) = 0 nanosleep({0, 100000000}, NULL) = 0 ... Really annoying bug, it puts servers down. Best regards, Fedir
