Hi,
we have a strange issue with solr: sometimes, usually everyday at around
midnight, solr becomes unreachable due to a high cpu load and high I/O
activity.
Our configurations are:
- Solr 7.7.3 on CentOS 7
- Dovecot 2.3.18 on CentOS 7
- /var/solr is around 250GB
- the Solr server has 40GB of ram / 2GB of swap (not used).
- SOLR_HEAP="30240m"
- sovecot is configured with "fts_autoindex = no"
It shouldn't be a RAM problem, as only 30% is used before restarting (
"memory":"8.6 GB (%30.4) of 28.3 GB"}).
Does anyone know what could be the cause of this behavior?
Thanks,
AG
