Should the issue be encountered, some of the symptoms you may expect to find include, but are not limited to:
- Applications may fail to start and/or core dump due to 'missing symbols' in linked libraries when the corruption occurs within the in-memory copy of the library. Applications currently running will not suffer any problems.
- pkgchk(1M) may fail the checksum for a file. If the file in question resides in-memory or within the filesystem cache this potentially corrupt version will be used rather than the on-disk copy which remains in tact and un-harmed.
Running pkgchk(1M) will show an error caused by the checksum failure of a file, eg:
The Service Processor (SP) may have been manually reset by the System Administrator or reset/paniced due to a problem on the SP itself. The trigger for the described issue is an SP reset no matter what the cause.
