Description Christina Scheinig

2021-08-26 10:54:16 CEST

In four customer environments the listener hangs on the servers, where the office 365 app is installed.

strace  -ff -t  -p 11479
strace: Process 11479 attached
16:52:39 read(17, 

netstat -tanp |grep 11479
tcp        0      0 10.200.1.13:48256         20.190.160.66:443       VERBUNDEN   11479/univention-di  
----------------------------------------------
strace -ff -t -p 17862
strace: Process 17862 attached
17:09:10 read(19,

netstat -tanp |grep 17862
tcp        0      0 10.200.1.1:58604          20.190.160.66:443       VERBUNDEN   17862/univention-di 
 
----------------------------------------------

Both still hanging processes are connected to 20.190.160.66:443

To restart the listener a kill -9 17862 was needed.
Just kill or stop the process was not sufficient
