SYMPTOMS
After you send a print job by using LPR to a TCP/IP print server, the TCP/IP print server may stop responding (hang) and causes over 90 percent CPU usage in TCPSVCS.



CAUSE
This problem occurs if the print job contains a value of 0x1B (ESC) at offset 0xFFF (4095). TCPSVCS has a routine to detect PCL or PostScript jobs; this routine enters an infinite loop under these conditions.
