Hi Krunal,

i'd suggest that you update to a more recent version of the server, if you use 
this in a production environment, e.g. 1.4.3 that will be released next week.

I think this is harmless. it says you are trying to forward 
a request which was already cancelled (this may happen due parallel
processing of the INVITE and CANCEL request). (quoted from some earlier 
discussion)

This are just warnings, you can ignore them. For the first one you need to 
release the transaction in the script, google for this error to get more 
informations.

This is not caused from a lack of SHM_MEM, its in the private memory pool. You 
need perhaps increase the PKG_MEM_POOL size in the config.h file. Also 
possible that you've a memory leak, see here for further troubleshouting 
hints: http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory

Not sure. :-) This are a lot of different errors. Before debugging this 
further, i'd suggest that you update to a newer version. Probably at least 
some of this problems are already fixed.
