SunOS4 has a kernel bug in the allocation of memory for the mbuf table. When it fills up, the result is a Panic the next time any routine tries to set something in an imaginary mbuf beyond the range of the table. Due to buggy browser behavior and the lack of a FIN_WAIT_2 timeout on SunOS4, "KeepAlive Off" is necessary to avoid filling up the mbuf table on busy sites. >Unformatted: (hope this goes to the right list. this is regarding PR#454 which i filed a few months ago.) i upgraded to Apache 1.2b10 and removed one of the two processors on the machine. it crashed within 24 hours. if there is anything i can do to help debug the situation, please let me know. this problem has been consistent since 1.2b8 -- 1.2b7 seemed somewhat more stable but still had the problem.
