The issue can be reproduced at will with the following steps:

1.Running production load of 150k transactions each in individual XML files.
2 Identifier has periodic failures due to out of memory errors.
3.Have temporarily mitigated by increasing JVMOptions -Xmx256m to -Xmx512m, however this does not resolve the memory leak as it will happen again after some time.

Due to this issue, users cannot use large volume transactions load.
