Catalog Sync CronJob Creation Interrupted by Unknown Reason

[Former Member]

Hello experts,

Hybris version 6.5

Catalog sync job defined with trigger via IMPEX:

INSERT_UPDATE Trigger; job(code)[unique = true, path-delimiter = |]; cronExpression ; sync myCatalog:Staged->Online ; 0 /5 ?

INSERT_UPDATE Job; code[unique=true]; rootTypes(code)[mode=append] ; sync $myCatalog:Staged->Online ; CategoryAttributeSettings

It works fine and creates new sync cron every 5 minutes. But after several days of execution cron creation stopped. I've tried to restart latest cron manually and saw in logs that there was additional job with status UNKNOWN. I've deleted it and tried to restgain - cron worked fine, but no new crons created after trigger interval.

I've solved the problem by deletening and inserting trigger again via impex.

My question - what could be the root of such problem? Probably, catalog sync must be performed only this way, and there sould be no manual sync? Or we must not restart server when job is running?

Please share an advice.
