Hello.
I have an issue: rouncube on large mailbox (289000+ messages in INBOX) not showing mail in INBOX folder. Other boxes, including my own, works fine.
My setup:
Mailboxes stored on NFS storage, perhaps this is an issue.
Debian 10 x86_64 with kernel 4.19.0-6-amd64 on a KVM virtual machine with 12 Gb RAM, host with SSD RAID10. No CPU/RAM lack issue
Roundcube 1.3.8, latest in Debian repo
Dovecot 2.3.4.1, has some NFS-related recommended config changes; indexes and volatile directory stored on local disk; fts_lucene enabled
MariaDB 10.3.18
Apache 2.4.38-3+deb10u3
PHP 7.0 (1024Mb memory limit, 50Mb max post size, 50Mb max upload size, 600 s max execution time)
How can I resolve this issue?
Thank you.
