I have attached dosdebug to dosemu when it hangs, and I got the following:
System state: running in real mode while in DPMI AX=0000 BX=800a CX=0000 DX=0003 SI=874c DI=023a SP=056c BP=c316 DS=c316 FS=0000 GS=0000 FL=3286 CS:IP=0522:0434 SS:SP=c316:05bc
0522:0434 53 push bx
What should I do? Thanks.

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.
