assertion failed: store_swapin.c:80

Hello squid users (and hackers),

Since I will need WCCP in my squid real soon now, I've switched
on of our proxies to 2.3S1. (2.2S5 + hno patch was rock stable
before).

Now my squid core dump on the following error:

2000/01/15 18:09:50| storeAufsOpenDone: (2) No such file or directory
2000/01/15 18:09:50| /var/spool/squid/01/01/4C/00014CCC
2000/01/15 18:09:50| assertion failed: store_swapin.c:80: "errflag <= 0"
2000/01/16 00:08:53| storeAufsOpenDone: (2) No such file or directory
2000/01/16 00:08:53| /var/spool/squid/01/01/4C/00014CD9
2000/01/16 00:08:53| assertion failed: store_swapin.c:80: "errflag <= 0"
2000/01/16 12:56:54| storeAufsOpenDone: (2) No such file or directory

2000/01/16 12:56:54| assertion failed: store_swapin.c:80: "errflag <= 0"

this one is probably harmless (short on asyncio threads?):

2000/01/16 13:04:10| aioWrite: EWOULDBLOCK
2000/01/16 13:04:10| storeAufsWriteDone: got failure (11)
2000/01/16 13:04:10| storeSwapOutFileClosed: swapfile 0002E80D, errflag=11
        (11) Resource temporarily unavailable

even after applying hno snapshot 20000116-2:

2000/01/17 15:06:46| storeAufsOpenDone: (2) No such file or directory
2000/01/17 15:06:46| /var/spool/squid/02/02/A6/0002A648
2000/01/17 15:06:46| assertion failed: store_swapin.c:80: "errflag <= 0"

I'm using async-io with NUMTHREAD set to 48, asyncufs in cache_dir argument
of squid.conf.

Well I admit I've browsed the source for only fifteen seconds... :-)

Anyone else bitten by this?

Cheers.
