Kopano Gateway Logon to http://localhost:236/: Too many open files (socket failed in tcp_connect())
-
Hi all;
I got a problem on an openSuse Tumbleweed Server (all Updates installed).
After 1 or 2 days of productive use, IMAP gets extremely slow and then wont work completely.
It repeats the following messages over and over:Nov 20 02:59:05 mail kopano-gateway[14468]: Logon to http://localhost:236/: Too many open files (socket failed in tcp_connect())
Nov 20 02:59:05 mail kopano-gateway[14468]: virtual HRESULT M4LMAPISession::OpenMsgStore(ULONG_PTR, ULONG, const ENTRYID*, LPCIID, ULONG, IMsgStore**): msp->Logon failed: failoneprovider (8004011d)

After a restart of the gateway (systemctl restart kopano-gateway) everything works fine again.
Encryption is via LetsEncryptHere is the gateway.cfg:
ssl_private_key_file = /etc/kopano/gateway/privkey.pem
ssl_certificate_file = /etc/kopano/gateway/cert.pem
ssl_protocols = TLSv1.1 TLSv1.2 TLSv1.3
ssl_prefer_server_ciphers = yes
pop3s_listen = *:995
imaps_listen = *:993
server_socket = http://localhost:236/uname -a
