[SR-Users] SHM error after few days...

[Krishna Kurapati]

Hi,

After few days of running kamailio (I am using TLS for client), suddenly I
see that the connections are being dropped.

When I restart kamailio, I see following errors:

Stopping kamailio:                                         [FAILED]
Not starting : invalid configuration file!

Bad address

My shared memory size for the kamailio is 4096M.

It started fine initially. However, after I noticed connection drops, I see
the above
issue.

THen I reduced shared memory to 2048M and it started fine.

I am under the impression that shared memory is just a filed I/O mapped
which can be several hundred gigs.

I looked at my filesystem. It looks fine

df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda3            958788080 200734800 709349640  23% /
tmpfs                  3975996         0   3975996   0% /dev/shm
/dev/sda1               495844     37498    432746   8% /boot


What could be wrong here?

Any help greatly appreciated.
