Lack of disk space

[ksv]

Dear all


I've started bulk mailing to leads (approximately 4500) via BPMN and faced with lack of recources (i gess disk space).
Overall the server crashed

there are files (binlogs) here, the size of which is 1 GB (more than 20 gb in total) -> /var/lib/docker/volumes/espocrm_mysql/_data

Can i delete them?

what are these files?

I think MariaDB to resolve this issue
