Symptoms

Internally detected issues can trigger a series of error log messages. The logs look alarming, but can be considered diagnostic in the case there is an actual behavioral issue that needs to be analyzed. The system reports the following messages in /var/log/apm: -- err tmm1[11197]: 01490514:3: 00000000: Access encountered error: ERR_VAL. File: ../modules/hudfilter/access/access.c, Function: access_slowpath_security_check, Line: 6648 -- err tmm8[18022]: 01490514:3: 00000000: Access encountered error: ERR_ARG.

File: ../modules/hudfilter/access/access.c, Function: access_check_uri_type, Line: 11219 -- err tmm8[18022]: 01490514:3: 00000000: Access encountered error: ERR_ARG.
