Try eqbc2, it's in the same folder and imo, better. I run my bc on a separate machine that has only a vendor account running on it and still would need to restart it after hours of gameplay because it would lag out or the clients would just stop entirely. eqbc2 I have running on that machine for weeks with no issues.
Also, if you're running Kiss, try editing your ini files:
EQBCOn=1
That allows kiss to broadcast certain messages and makes watching the other toons a bit easier.
