<DIV>Yes, we did check. We tried setting env var TMPDIR, we got pretty much</DIV>
<DIV>the same error, with the tmp being in the TMPDIR. We also checked the</DIV>
<DIV>temp files, and the file that caused the error was there, 360M of it.</DIV>
<DIV> </DIV>
<DIV>I read the code of clog_buffer.c, the ierr returned by the write is int, but block size</DIV>
<DIV>is unsigned. I don't know if this is the problem. I modified the error message</DIV>
<DIV>to print more info. But the peroson running my application is on vacation for a </DIV>
<DIV>week. I will not be able to run it to see more info.</DIV>

The error message below shows that /tmp_proj is used
for local clog2 file, can you check if you have write
permission to /tmp_proj ?
