NXLog client failed to read config cache
Hi,
This error is found in the logs nxlog client enterprise from time to time:
2018-12-26 00:00:00 INFO LogFile C:\nxlog\data\nxlog.log reopened
2018-12-26 00:00:00 INFO inode changed for 'C:\nxlog\data\nxlog.log' (79652->79655): reopening possibly rotated file
2018-12-26 00:00:11 ERROR failed to read config cache; string expected for config cache version
2018-12-26 00:00:11 ERROR exiting...
I use recommended configuration for nxlog client:
PersistLogqueue TRUE
SyncLogqueue TRUE
CacheFlushInterval always
CacheSync TRUE
<Input in>
Module im_file
File 'C:\logs\????-??-??.log'
BufferSize 2500000
SavePos TRUE
</Input>
<Output out>
BufferSize 9500000
Module om_batchcompress
Host 192.168.1.100
Port 1514
</Output>
Why is this happening? Thanks for any ideas!
I use
- client nxlog-3.2.2002
- server nxlog-4.1.4046
This issue is normally seen when an older version of NXLog creates the /opt/nxlog/var/spool/nxlog/configcache.dat file, a newer version of NXLog is installed, and then tries to read the old version.
This is due to a format change in configcache.dat between certain versions (adding a version number in your case).
Resolution would be to stop NXLog service, remove /opt/nxlog/var/spool/nxlog/configcache.dat, start NXLog service.
Your 3.2.2002 version is quite old. It would be a good idea to update it when you can. There are a lot of fixes between that version and current.
Thank you,
jesse
