Fail to preallocate additional space for store file

Strange error in debug log.

Any Idea?

I presume this is Neo4j 4.4.4? correct? if not can you provide further specifics.

Does your file system have ample free disk space, i.e. from a linux command run df -h

[kcw]

Yes. 4.4.4

I have plenty of disk space.

@dana.canzano Any Ideas?

@kcw

hard to say,
is there any context about this error?
Is this error encountered at time of startup? at time of online-ing the database? at time of backup ?

does linux command

ulimit -a

report an unlimited file size?

and if i forceibly set a exceeding low limit as a test I can reproduce a File size limit exceeded(core dumped), though not exactly the same but similar.
And if so this doesnt appear to be a Neo4j failure per say, but more so behaving as expected given the low file size limit of linux

@kcw

any progress? was the OS limiting the max file size?

[kcw]

Yes, it was!!!

Thanks.

@kcw
great to hear it wasnt directly a Neo4j limitation/issue
