Re: [SR-Users] Fwd: Websocket immediately disconnecting

Further hints here: the allocated size for private memory is rather low at 4MB (-M 4), try at least with 8. The set also memjoin=yes global parameter.

Cheers, Daniel

Can you try increasing the memory?

As a supplement to the above:

Kamailio is launched with -m 64 -M 4. 
After researching, I've doubled the values and we'll see shortly.

Hi David,

Thanks for your reply.

After increasing the verbosity of the debugging, I found the
following entries. So am I understanding the log correctly: the
websocket module is trying to get some free memory (from Kamilio's
general pool?). It doesn't receive any yet proceeds with parsing
the response (I get this same parsing error even when it's
working) and ultimately, it doesn't register the websocket?

I appreciate your (or anyone's) thoughts.

Regards, Tom
