I can't see that this has anything to do with mod_wsgi. You need to find the developer of the software you are using and ask them instead.

Hi GrahamDumpleton,
This is not for any kind of support here, it was just a query if any one facing this similar issue for json library.
We are debugging and trying to find the memory corruption, but not reach to any conclusion as it is occurs randomly.
So checking if any one face similar issue ?

Anyway thanks a lot.

Regards,
Alok
