ethereal Capture Problem

OS: SuSE 9.3 Pro In attempting to run tethereal capturing traffic on two different systems using this command: tethereal -a filesize:30000 -b 100:120 -i eth0 -q -w /var/log/eth0.log One system is running ethereal v0.10.9-4 and it works as it has since 9.1, namely capturing up to 30MB of data or captures for up to 2 minutes rotating capture files up to a maximum of 100 files before overwriting the first one. Files are named eth0_00001_, eth0_00002_, etc. However on the system running the latest v 0.10.11-2.1, the same capture command does not increment the file sequence number which will eventually exhaust all diskspace. Files are named eth0_00001_, eth0_00001_, etc. Did they introduce a bug into [t]ethereal? Thank you, Lucky Leavell
