9.7.2 The SCSRESPCNT Parameter Description:
The SCSRESPCNT parameter controls the number of response descriptor table (RDT) entries available for system use. An RDT entry is required for every in-progress message exchange between two nodes. Symptoms of entry shortages: A shortage of entries affects performance, since message transmissions must be delayed until a free entry is available. How to determine a shortage of RDT entries: Use the SDA utility as follows to check each system for requests that waited because there were not enough free RDTs.

SDA> READ SYS$SYSTEM:SCSDEF <---------(Docu error dir is: SYS$LOADABLE_IMAGES)
%SDA-I-READSYM, reading symbol table SYS$COMMON:[SYSEXE]SCSDEF.STB;1
SDA> READ SYS$loadable_images:SCSDEF
%SDA-I-READSYM, 13728 symbols read from SYS$COMMON:[SYS$LDR]SCSDEF.STB;1
SDA> EXAM @SCS$GL_RDT + RDT$L_QRDT_CNT 8044DF74: 00000000 "...."
SDA>
How to resolve shortages: If the SDA EXAMINE command displays a nonzero value, RDT waits have occurred. If you find a count that tends to increase over time under normal operations, increase SCSRESPCNT.
