server atd[10055]: File a0001a015f162e is in wrong format - aborting

Hello Members,

I want you to be aware of the strange issue that I faced on one of our CentOS servers. System log file /var/log/messages was flooded with the error message as below. The log file was so large with these messages that the server ran our of disk space.

server atd[10055]: File a0001a015f162e is in wrong format - aborting

This should be due to the at command which was not executed properly. You will have to find the job number and then remove the job from the queue.

# atq a0001a015f162e

It should show an output as below. This will help to get hold of the job number.

# 15 2013-10-05 00:42 a root

Here, the job number is 15. Use the command below to remove the job number from queue.

# atrm 15

This should stop occupying the disk space on the server.
