CentOS - Jun 2018 - Firefox and Thunderbird freeze/crash followed by "nfs4_reclaim_open_state: Lock reclaim failed!" syslog messages

Hi,

since I updated my workstation from CentOS 7.4 to 7.5, Firefox and 
Thunderbird (both 52.8.0, from CentOS repos) regularly freeze (or crash) 
and cannot be restarted afterwards.  Trying to start them results in a 
"Bus error (core dumped)" (Firefox) and "Killed"
(Thunderbird).  The
system log then shows:

      kernel: NFS: nfs4_reclaim_open_state: Lock reclaim failed!

each time I try to start the applications (our homedirectories are 
mounted via NFS4).  As far as I can see, no other applications are 
affected.  The workstation needs to be rebooted to fix the situation.

Has anyone else seen that or knows how to debug or fix this issue? I 
tried with strace and wireshark w/o finding anything helpful.

Cheers
frank

I'm not sure what the el7 default for the Firefox 
'storage.nfs_filesystem' pref is - but you could try setting it to 
'true' to see if that makes a difference ?

I'll give that a try.  Thanks for the hint.

That's one of Firefox' problems: There doesn't seem to be a decent 
documentation for all the available configuration settings.

I was afraid someone would say that :-).  I am currently at 
3.10.0-862.3.2 and downgrading to a 3.10.0-6xx kernel breaks some of the 
other packages.

Is the mentioned bug documented somewhere?

Cheers
