Just compiled swish-e-2.0.5 on sparc64-Linux (2.2.17-RAID); './configure',
'make', 'make test' all without errors.  Running HTTP method to index
small chunks at a time, then merge them to a larger database, but coming up
with a endless-loop, but only *sometimes*...

Sample files...

-rw-r--r--   1 ericj    staff      158642 Feb 21 17:09 swish.2
-rw-r--r--   1 ericj    staff     1048472 Feb 21 17:32 swish.4
-rw-r--r--   1 ericj    staff      873571 Feb 21 18:23 swish.x
-rw-r--r--   1 ericj    staff       67552 Feb 21 18:07 swish.y


Sample command...

% swish-e -S http -c conf.x
..(writes to 'swish.x')...

% swish-e -w testing -f swish.x
(works well, no loop)

% swish-e -w test -f swish.x
(loops with data below)


Strangely *both* searches ('test' and 'testing') work correctly in the
other files (swish.2, swish.4, swish.y) with either 'results' or 'no
results' outputs.  On 'swish.x', however...

	# Swish-e format 2.0
	# 
	# Name: Index of http://www.eskimo.com/
	# Saved as: swish.x
	# Counts: 14763 words, 178 files
	...
	# IgnoreFirstChar: "'(
	# IgnoreLastChar: "'),.;
	# SWISH format 2.0
	# Search words: test

At which point it hangs.  Running this through strace brings up (one
username changed to '[edit]'):

Searching for 'testing' on the same database ends with (starting at the
same point):

(back to shell prompt)


Since 'brk' is a memory structure (change data segment size), I made sure
my ulimits were unlimited:

% ulimit -a
time(cpu-seconds)    unlimited
file(blocks)         unlimited
coredump(blocks)     1000000
data(kbytes)         unlimited
stack(kbytes)        unlimited
lockedmem(kbytes)    unlimited
memory(kbytes)       unlimited
nofiles(descriptors) 1024
processes            2028



The same "brk...read...read...read...read..." loop happens during a -M
merge using that swish file.

It's a stumper at the moment.  Any ideas out there?

It would be a "production" environment eventually, so I'd prefer to stick
with the "stable" one (although today's 2.1 devel version compiled, it
failed 'make test's filesystem test).

Am trying 'swish-e' as the older 'swish' dumps core during some filesystem
indexing as well (although I haven't tried that with the unlimited 'stack'
size).


Thanks for any ideas...
