  It's a problem with rid's berkeley db. It's a known issue that has
  been plaguing us for a while. Let me try to fix.

  Here is apparently how we find out about the log sizes

aras at nebka:~/acis/RI/data$ db4.6_stat -l -h .
0x40988 Log magic number
13      Log version number
31KB 256B       Log record cache size
0       Log file mode
10Mb    Current log file size
1409130 Records entered into the log
347MB 192KB 618B        Log bytes written
0       Log bytes written since last checkpoint
666610  Total log file I/O writes
2099    Total log file I/O writes due to overflow
664731  Total log file flushes
243     Total log file I/O reads
475089  Current log file number
10465668        Current log file offset
475089  On-disk log file number
10465668        On-disk log file offset
4       Maximum commits in a log flush
1       Minimum commits in a log flush
96KB    Log region size
12      The number of region locks that required waiting (0%)

  According to

http://www.cjc.org/blog/archives/2006/08/22/cyrus-imap-log-and-cache-settings/

  I created file 

aras at nebka:~/acis/RI/data$ cat DB_CONFIG 
set_cachesize 0 2097152 1
set_lg_regionmax 1048576 

  and run

aras at nebka:~/acis/RI/data$ db4.6_recover -h .

aras at nebka:~/acis/RI/data$ db4.6_stat -l -h .
0x40988 Log magic number
13      Log version number
31KB 256B       Log record cache size
0       Log file mode
10Mb    Current log file size
0       Records entered into the log
0       Log bytes written
0       Log bytes written since last checkpoint
0       Total log file I/O writes
0       Total log file I/O writes due to overflow
0       Total log file flushes
707     Total log file I/O reads
475089  Current log file number
10465816        Current log file offset
475089  On-disk log file number
10465816        On-disk log file offset
0       Maximum commits in a log flush
0       Minimum commits in a log flush
1MB 32KB        Log region size
0       The number of region locks that required waiting (0%)

  Now shows that the log file size is larger.

  I try

aras at nebka:~/acis/RI$ updareq RePEc /tor/tecipa

  and the log shows

Thu Mar 25 21:29:16 2010  request:
 source: /home/aras/acis/bin/updareq [32355]

Thu Mar 25 21:29:17 2010 time:  1 wallclock secs ( 0.26 usr +  0.03 sys =  0.29 CPU)

  You are not a computing genius. Tonight it's my night.
