https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250576 Bug ID: 250576 Summary: PHP-FPM processes hang in UFS-state Product: Base System Version: 12.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: chris@cretaforce.gr This issue happened in 3 different servers the last months. Some PHP-FPM processes hang in UFS-state. The websites that cause the hang are all Prestashop and it's related to the= ir var/cache files (I believe it happens when they clear the cache and the fil= es are regenerated). This is a php-fpm process that hang: procstat -kk 73548 PID TID COMM TDNAME KSTACK 73548 100630 php-fpm - mi_switch+0xe2 sleepq_wait+0x2c sleeplk+0x185 lockmgr_xlock_hard+0x1f5 __lockmgr_args+0x2bf ffs_lock+0xa5 VOP_LOCK1_APV+0x7c _vn_lock+0x44 vget+0x4a vfs_hash_get+0xb0 ffs_vgetf+0x3f softdep_sync_buf+0xbee ffs_syncvnode+0x26f ffs_truncate+0x71b ufs_direnter+0x5f8 ufs_makeinode+0x5fb ufs_create+0x34 VOP_CREATE_APV+0x76= =20 procstat -kk -a : https://www.coderz.gr/ufs/procstat.txt mount | grep home : https://www.coderz.gr/ufs/mount.txt dumpfs /dev/mirror/gm0p7 : https://www.coderz.gr/ufs/dumpfs.txt I have to force reboot the server as /home is not possible to clean unmount. Then I run fsck which fixes some issues because of the unclean reboot. Then= I run fsck again that shows no errors. Then I mount /home and first rename the cache folders and finally delete var/cache and allow it to regenerate prestashop files. But the same issue happens again after few days. Any idea how to troubleshoot it? --=20 You are receiving this mail because: You are the assignee for the bug.=
