<p class=MsoNormal><span style='font-size:12.0pt'>I have a question about the

<p class=MsoNormal><span style='font-size:12.0pt'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt'>Recently our EPrints server (SuSE
linux runs EPrints 3.3.10) gets very high disk utilisation in the partition “/tmp”.
By checking this partition, I found there are several temporary folders created
and written by the “eprints” user. The files in that temporary
folder look like:<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt'>At the beginning, I thought
it might be an attack, however after very heavy security scanning we found
there are no obvious vulnerabilities. Also I found later some of those files
disappeared while some folders still remain in /tmp, which consumes a lot of
disk space (approx. 1Gb to 2Gb).<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt'>After reading some messages
in the archived tech group emails, I highly doubt whether those files are
temporary files written by EPrints system when doing indexing or other backend
jobs. We have been running EPrints software for many years and this issue is
recently new after we upgraded to version 3.3.10. I wonder whether there might
be a bug in the 3.3.10 version which fails to remove those temporary files
after backend jobs complete. <o:p></o:p></span></p>

much!<o:p></o:p></span></p>
