...d will suddenly start using 100% CPU and sit there. Attaching strace to this process shows nothing -- literally, it's making no system calls whatsoever. Attaching gdb to this running process and using "next" reveals that it's doing the following: memcpy() -> tdb_read() -> tdb_find() ... and then stops in tdb_find() claiming there's no more line numbers to look at. So on the tentative premise the problem lies in tbd_find(), I didn't find anything obvious, but noticed the following call-chain is happening: tdb_find() |---> tdb_key_compare() +---> tdb_parse...

...e live tdb 100% robust against accidential (or even malicious) corruption. 3 aspects here: * The recent hardening patches in tdb make me confident we improved here a lot. * We need bullet-proof circular chain detection. We need to put the same logic that tdb_check has into the normal flow of tdb_find(). * We need record crc checks. Easiest would be in gencache "user space", but tdb-level we could benefit too.

Hi all, I have a midsize AD domain with some 50k users but only 100 workstations joined. Sometimes I find server CPU throttling at 100%. In order to let it drop and have smooth performance I delete cache: systemctl stop samba net cache flush systemctl start samba First of all, is it needed a samba stop to flush the cache? Even if cache flush does the job to restore performance, I am clueless
