I think it is the silver salts collected by the fixer during fixing that became unstable, and the silver precipitates into the fixer. Did you fixed the four rolls within short periods of time (like a couple of weeks), or the used fixer was left there for a long time? If the latter case, the silver salts in solution will get unstable with time.
If you development sessions are few and far between, you should make fresh fixer the next time you plan to use it. And of course you should store fixers in the dark, not just kept in a dark bottle.

I would pour the fixer through a paper coffee filter then take a piece of film leader and agitate it in the fix untill the film clears. If the film clears in say 2mins then fix your next film that you develop for 4mins. Just double the film clearing time.

Fixer usually yellows or gives off a sulfuric smell when it's decomposed. Never heard of completely black fixer before.

My TMAX fixer goes a very slight yellow, and then clears after 10 minutes after use. I fix maybe 4-6 films (much less than Kodak say is possible) then pour it out. Its not like it breaks the bank.
