gromox-3.7.244.m3ff60c1 - gromox-imap stops responding

gromox-imap stops responding to requests e.g. by Mozilla Thunderbird or other IMAP clients without any debug or error messages. Running `openssl s_client -connect <server>:993` shows CAPABILITY response, but any command afterwards is not processed (no response). I enabled in `imap.cfg`: ``` #Debug imap_cmd_debug=2 imap_log_level=6 ``` Gromox is running behind haproxy: `gromox.cfg`: ``` #HA-Proxy imap_accept_haproxy=2 ``` On restart of the defunct `gromox-imap.service` the systemctl-triggered `SIGTERM` runs into timeout and leads to `SIGKILL` in order to achieve a restart at all. After the restart Thunderbird immediately fetches new emails and everything returns to normal till next hangup. I noticed that supported also has a new version, which fixes my both other issues, so I will try `gromox-3.7.228.7df9ab0-6.1.aarch64` first - if it does also not work, I am going to downgrade to 3.7.6
