Hi,

The process is one of the UDP workers actually. You can see that error occurred in receive_msg: ERROR:core:receive_msg: no pkg mem left for sip_msg. I also checked that with MI 'ps' command. Usually I got it from the single process.

Hi Alexander,

The warning is actually reporting a highly fragmented memory and not a lack of memory. It reports 303 available Mb, but not a single continuous slot for like 33K.

By doing an MI "ps", could you identify the name/type of the process reporting this issue ? do you get it from a single process or from multiple processes ?

What memory management and allocator are you using?

I had similar issues using opensips 3.2.7 and the quick workaround was to change from F_MALLOC to HP_MALLOC. But I thought there should have been fixes for such issues in newer versions, so your issue might be different.

    Hi,

    of course I did. It doesn't help.
