Package: samba Version: 2:4.2.10+dfsg-0+deb8u2 Severity: normal Dear Maintainer,
since the samba version in jessie was updated to 4.2 we have an issue with our server that renders shares unusable. After they've been accessed for a small amount of time, the log constantly shows: single_accept_connection: accept: NT_STATUS_TOO_MANY_OPENED_FILES In fact each samba process' /proc/*/limits file shows: Max open files 1024 4096 files >From what I read on the Internet this limit seems to be quite low for a >frequently used Samba server. ulimit -n in ssh shows 65536. I tried to increase the limit for samba by adding a nofile configuration to /etc/security/limits.conf as well as adding a max open files configuration to /etc/samba/smb.conf but it did not have any effect. I also added pam_limits.so to /etc/pam.d/samba as I found that on the Internet, however I doubt that it makes any sense in my situation as it is not about per-login (smbd) processes but the limit is set for the main samba process and every child. I'm puzzled how to change the limit and why this shows up after the upgrade. The server worked fine before.
