<*Ding!*> this finally rang a bell. Maybe the wrong bell, but maybe not.
Are you using BSD sockets much? Check your buffers:
:nettool.net.sys "resource;display;quit"
Check the number of TCP connections in use versus your max defined:
:print tcpuse
symopen symnsxpt.xpt0407.telesup
var tcp_kso_ptr:lptr=[c0000000+#333*8].[c0000000+#333*8+4]
var max_cons = &
symval(tcp_kso_ptr 'tcp_kso_block_type.TG_MAX_CONNECTIONS_ALLOWED')
var cur_cons = &
symval(tcp_kso_ptr 'tcp_kso_block_type.TG_NUMBER_OF_OPEN_CONNECTIONS')
symclose symnsxpt
wl cisetvar ("tcp_cur_conns", !cur_cons)
wl cisetvar ("tcp_max_conns", !max_cons)
c
:debug
DEBUG/iX B.79.06
HPDEBUG Intrinsic at: a.009dc390 hxdebug+$e4

TRUE
:showvar tcp@
TCP_CUR_CONNS = 93
TCP_MAX_CONNS = 4096
There was a sneaky problem in 5.0 with "persistant" BSD sockets staying in
use although they would only show up in debug. When this happens, it
appears as though network services are down (but they aren't). I have seen
cases of running out of connections and/or out of buffers causing those
unusual VT errors. When transport gets hung up, the TCP keepalives soon
disappear (or get rejected going out) and the VT sessions drop as if the
session was aborted on the client.
That's my guess for what it's worth :-)
You should also try the NSCONTROL KILLSESS= to get rid of the pervasive
sessions.
