"Segmentation Fault" error usually caused by shared memory allocation. You may need to remove orphan shared memory segments and semaphores, or increase share memory queue sizes. To determine if it's a share queue memory size, check for the following symptoms:

A. Start SharePlex:
$ ./sp_cop -u2100 &
[1] 12337
[1] + Segmentation Fault sp_cop -u2100 &

B. Start qview:
$ qview -i
qview> qsetup 2100
Segmentation Fault

C. Look in $vardir/data/event_log
No indication of error or sp_cop starting

If the 3 above conditions are true, you need to increase your SP_QUE_SHMSIZE and SP_QUE_SHMDBUF sizes. The problem occurred due to unable to initialize queue.

SP_QUE_SHMSIZE (default 16777216) 32M (33554432) 64M (67108864) 128M (134217728)
SP_QUE_SHMDBUF (default 8192) 16K (16384) 32K (32768) 64k (65536)

i.e.

Edit (vi) your $vardir/data/paramdb and append

SP_QUE_SHMSIZE "67108864"
SP_QUE_SHMDBUF "32768"

Start sp_cop (./sp_cop -u2100&)
