Hello David,
The problem looks like the session table is being corrupted.
I modified the schema using: ALTER TABLE sessions CHANGE a_session
a_session LONGBLOB;
Now everything seems to be working fine.
By the way, I am also using a virtual machine. 256Mo were enough for
3.8.0. I increased the available memory to 512Mo but this did not
solved the problem.
I hope this trick will solve your problem.
Regards
Sebastien
