I tried to reproduce the problem using the -D9+Mr log. However, this time, dosemu actually crashed as opposed to just hang. The complete log is 33M, so I am just pasting the end of it here. Please let me know if there is a place where i can email you the complete log.
Thank you for helping me.

No, that is not possible. DPMI server runs in protected mode, so it has to be part of dosemu and a server cannot be installed from the v86 task. It is the same reason why you can't use another 386 EMS manager under dosemu, because the EMS manager runs in protected mode in order to use the 386 paging unit.
Also, usually DPMI servers that are not integrated into the EMS manager will use VCPI to enter protected mode, since the EMS manager is already running in protected mode and provides a VCPI interface in case another program wants protected mode. Using VCPI is unfortunately also impossible under dosemu, not a fault of dosemu but the fault/intent of VCPI design.
