this issue was fix between 05/2017 and now, putting a new version of FS git master solves my issue. sorry for the noise. On 01/22/2018 05:40 PM, António Silva wrote:

hi,

After a few weeks running fs without issues, i got the error "Too many open files", i understand that i reach the limit of allowed open files in the system. But it must be trigger for some "zombie fds" opened..

Is there a way to get the "zombie" fds open by fs?

I use lua scripts to check db mapping, so in every script i make sure to call dbh:release() before returning. I also use esl sockets to check FS events.

in the running process i have the following limits:

cat /proc/10975/limits

currently i see the number of files change:

I see lot of entries: COMMAND    PID USER   FD   TYPE             DEVICE  SIZE/OFF NODE NAME freeswitc 2429 root *257u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *258u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *260u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *261u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *262u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *264u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *265u  0000               0,11         0 10734 anon_inode freeswitc 2429 root *266u  0000               0,11         0 10734 anon_inode

grep "0000" openfiles | wc -l 78951

but I don't understand the output for the TYPE= "0000"...

thanks for the help.
