#5078 Random Error - Bad Header

[IMT]

Operating system CentOS Linux 7.4.1708
Webmin version 1.872

Continuously i get a "Bad Header" with webmin. Already switched theme from Authenic theme to gray-framed theme. problem stays. Some times there it's possible to work a few minutes without problems.
Server restart/ webmin restart doesn't help. This server was running ok for a year now and this error pops-up every time. Also the error log is full with bad header error messages.
