Recently we always met the following errors after we updated EOS fuse from 4.2.7 to 4.2.18 at IHEP site. These errors may also lead to eosd segment fault sometimes. The version of EOS server is also 4.2.18. Is there anybody can help us? Thanks a lot.

This is an important issue, we at the JRC have observed similar errors ourselves, but we have observed them with all client and server version combinations of EOS.
We never managed to get the real issue here, and therefore its very difficult to generate a meaningful bug report on the problem.
It would be great if we could find more about that problem.
Actually, coredump of eosd has been generated by abrtd, but it was deleted immediatly.

I have set ‘OpenGPGCheck = no’ in the file abrt-action-save-package-data.conf，but it still doesn’t work.
Who knows how to make abrtd keep the coredump file? And it would be helpful for developers to find the bugs.
