Re: Problem with DiskDataStore

2018-04-19 Thread Claudia Hirt 
Seems as if this was caused by WICKET-6471 
 - FileSystemResource 
file descriptor leak.

We did an upgrade to wicket 7.10 and hopefully it will solve it.

Thanks anyway!

Best regards,
Claudia Hirt

Hi all,

I get the following error when there are a lot of sessions on the system:

This leads to a total breakdown of file system in my case.
I saw this already was an issue here:

 but there was no solution.

Are there some settings in PageStore or anything to avoid this problem?

Best regards,
