If other users can open the same folder, then the cyrus.header and cyrus.index files must be sane.As an experiment, you could move your seen file from lang.seen (or whatever it's called) to lang.seen.bak. Then connect to IMAP as yourself and try to open the folder. If it works, then it must have been a corrupted seen file, and you can use skiplist.py to recover as much of it as possible.Ok, the good news is that this seems to be the problem. unfortunantly the skiplist recovery tool is not working. # ./skiplist.py dlang.seen.bak >dlang.seen.txt Traceback (most recent call last): File "./skiplist.py", line 172, in <module> values, keys = getkeys(fp) File "./skiplist.py", line 152, in getkeys spointer = unpack('>I', str_p)[0] struct.error: unpack requires a string argument of length 4 # file dlang.seen.bak dlang.seen.bak: Cyrus skiplist DBI tried enabling debug mode in skiplist.py and I'm not seeing anything different. This confuses me. I'm not that familiar with python, but as I read the code, get_header() should be writing a bunch of stuff before it gets to the getkeys() section that failing.Hmmm, I haven't looked at the code in skiplist.py much. I have an older version of skiplist.py, which I have attached to this email. Honestly, I haven't used this since I upgraded to Cyrus v2.3.something. I think there were some bugs in skiplist on the older versions. :)Give the attached skiplist.py a shot! Worst case, you'll have to start over with no Seen history. :(It dies as well. It turns out that it's sending the debug messages to stdout not stderr. It looks like it processes 96 sections before it dies.with debug off I just get the error, with debug on I get a bunch of stuff that looks fairly similar, ending with:[*] ------------------------------------------------------------------------------[INORDER] Record type INORDER [INORDER] Key size 16 (16) [INORDER] Key String 7536cca646f98c5d [INORDER] Data size 259 (260)[INORDER] Data String 1 1351316330 4755 1351316487 1,285,528,596,807,811,984:1003,1005:1010,1012,1014,1016,1018:1019,1075,1239,1619,1821,1920,2409,2511:2513,2646,2713,2787,3076,3080:3081,3084:3085,3090,3124,3126,3148,3160,3385,4056,4108,4186,4221,4256,4320,4390,4401,4585,4618,4627[INORDER] Skip pointer 16264 [INORDER] Total Skip pointers: 1[*] ------------------------------------------------------------------------------[INORDER] Record type INORDER [INORDER] Key size 16 (16) [INORDER] Key String 782cc11f4fb291b5 [INORDER] Data size 127 (128)[INORDER] Data String 1 1351316303 46217 1351316313 1:13755,22847:22986,26559:26563,26565:26749,29906:29910,30316,Traceback (most recent call last): File "/home/dlang/skiplist.py", line 167, in <module> values, keys = getkeys(fp) File "/home/dlang/skiplist.py", line 147, in getkeys spointer = unpack('>I', str_p)[0] struct.error: unpack requires a string argument of length 4with >24k messages in my inbox, I really hope I don't loose too much of my seen data. anyone else have suggestions?David Lang
