Opened: Jun 22, 2016
Severity: 2-Critical

Symptoms

In certain situations, the MCPD process can leak memory. This has been observed, for example, while updating large external data-group file objects. Each time an external data-group file is updated, MCPD's memory utilization grows a little bit. Once enough iterations have occurred, the system may no longer be able to update the external data-group file, but instead return the following error message: err mcpd[xxxx]: 01070711:3: Caught runtime exception, std::bad_alloc.

Impact

The system may no longer be able to update the external data-group file object. It is also possible for MCPD to crash, or be killed by the Linux OOM killer, as a result of the memory leak.

Conditions

So far, this issue has only been observed while updating a large external data-group file object.
