These spooler errors started appearing around the same time for six different servers where the robot is installed.
Apr 25 06:00:20:402  spooler: QueueAdmin - expire old messages
Apr 25 06:41:08:288  spooler: rdbReset - open (q2.rdb) failed (Invalid argument)
Apr 25 06:41:08:288  spooler: FlushMessages - unable to reset out-queue
Apr 25 06:41:08:293  spooler: FlushMessages - aborting
I have checked the firewalls, file permissions, disk space and they all seem to be fine. I have also deleted both of the .rdb files.. Everything has been reset or restarted at least once to fix the problem.
I have also updated to the latest version of the robot 7.93 though the problem originally occurred on 7.8
- UIM 8.5.1
- Robot/spooler 7.80 and 7.93
This alarm will be published if the spooler probe fails to create a new queue file (q1.rdb/q2.rdb)
In general these alarms are usually due to an environmental issue which is preventing the spooler probe from accessing one of these queue files. The out-queue corresponds to the q2.rdb file. The spooler will not clear this alarm, even if the condition that causes the alarm to be generated in the first place is cleared on the robot. If you continue to receive alarms and QoS from this robot and you see that the \Nimsoft\robot\q1.rdb file is not continuously growing in size, then the intermittent problem is most likely environmental.
It is advisable to have the robot System admin check for these common causes for this alarm:
On the other hand, if you are not receiving any messages from the robot generating the alarm and the q1.rdb file is growing in size, it may mean that the q2.rdb file is corrupted. To look into this further:
- There is no hard drive space on the robot disk volume or the drive is read-only
- The robot does not have proper permissions
- There are 2 spooler services running
- There is AV software scanning/locking the files in the nimsoft directory which is preventing the spooler service from functioning correctly.
- (you must create a full exception for all UIM/Nimsoft programs on the robot)
- There is a file system problem on the system where the robot is installed
- Backup software is locking the files
1. Stop the Nimsoft Robot Watcher service on the robot
2. Save off a copy of the q2.rdb file and remove it from the \Nimsoft\robot directory
3. Start the Nimsoft Robot Watcher service
The spooler will create a new q2.rdb file and if the problem was due to a corrupted q2.rdb file, messages should start flowing again.
An analysis of the archived q2.rdb may show corrupt data via illegal characters which could have been disrupting the normal data flow.
Additionally, robot machines that generated spooler alarms may be:
- Unreachable via ping
- Decommissioned (non-existent / unknown)
- Moved to test environment
- Have host intrusion protection IPS installed on them (e.g., in /opt/Symantec)
