Application stuck in creating XercesDOMParser object

[Mollyn, Priya]

Hi,

 

We are using Xerces C++ Parser 2.6 version, and are noticing high cpu issue, and when we attach gdb, it is pointing to malloc in XercesDOMParser object creation. Has anyone seen this issue ? Any idea on how to fix this ? The issue is intermittent, not easy to reproduce, but so far happened couple of times already. Once this issue happens, the process seems to be stuck doing nothing.

 

Any help would be appreciated.
