Hi again,



I had the error now again: 335544382. Can't allocate difference page

I think that happened when I tried to execute
ALTER DATABASE END BACKUP

I also found the following in syslog:

Feb 19 04:24:13 kernel:traps: firebird[16552] trap invalid opcode ip:7fabfa1bec19 sp:7fabd19c6950 error:0 in libpthread-2.23.so[7fabfa1b2000+17000]

Sadly I do not have a coredump (as that part of the harddrive is not mounted writeable).
But also notice, that the firebird database partition still has >400GB free space.

Also I found a "335544363. no transaction for request" error, but I have no timestamp and cannot correlate it with the crash.
However I got the impression that this happened really short after the crash (and we are using a connection pool).

This is currently firebird 3.0.2.
Does the information above help in any way?

We are preparing an update to the system that will make the coredump position writeable.
But then we do not want to wait for the next problem at the customers site.

Steffen
