wallace needs a restart about every other week

[Thomas Spuhler]

About every other week, all e-mails get stuck and I need to restart wallace (systemctl restart 
wallace)
After that the e-mails are being delivered.
Does anybody else experience this and what is the solution?

I am using wallace-0.5.16
