OK, a little more fooling around. term% grep full *.c
(wait about a second, hit DEL) grep: can't open apic.c: 'apic.c' './sys/src/9/pc/grep' does not exist grep: can't open apm.c: 'apm.c' mount rpc error grep: can't open archmp.c: 'archmp.c' mount rpc error grep: can't open bios32.c: 'bios32.c' mount rpc error grep: can't open cga.c: 'cga.c' mount rpc error etc. in fact I get an error for each file in the directory. I also get one of these for each file. mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc/devlml.c rep 0x16d7010 tag 3 fid 533 T112 R111 rp 3 mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc/devlml.c rep 0x16d7010 tag 3 fid 533 T120 R113 rp 3 mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc rep 0x16d7010 tag 3 fid 524 T110 R121 rp 3 mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc/devmoipv6.c rep 0x16d7010 tag 3 fid 534 T112 R111 rp 3 mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc/devmoipv6.c rep 0x16d7010 tag 3 fid 534 T120 R113 rp 3 mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc rep 0x16d7010 tag 3 fid 524 T110 R121 rp 3 mnt: proc grep 90: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc/devrtc.c rep 0x16d7010 tag 3 fid 535 T112 R111 rp 3 so what is interesting is that the grep did not die. It keeps trying to open files and keeps failing. And then, finally: term% ls ls: .: clone failed term% So, we see lots of guys with the same tag, with a T and R mismatch, with T and R like open and clunk, with the apparent problem that they are all using tag 3. I'm wondering if there is not a problem with the way tags are flushed when there is an interrupt. As an experiment I commented out the free in the freetag code. Better: now I just get this: mnt: proc grep 78: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc/apic.c rep 0x1491c60 tag 2 fid 454 T120 R117 rp 2 after the DEL, TCLUNK gets an RREAD (which makes a sort of sense) and the when I ls . mnt: proc rc 80: mismatch from /net/tcp/0/data /n/o/sys/src/9/pc rep 0x1491c60 tag 2 fid 421 T110 R121 rp 2 Twalk for the ls gets the RCLUNK And from that point on it's all over. Interesting. ron
