[Gems-users] Lazy TM hangs during commit

[Gwendolyn Voskuilen <gwendolyn.voskuilen@xxxxxxxxx>]

Hi,

I
 am running TM using lazy (LL) on the the stamp benchmarks. The threads 
keep getting stuck at commit because one thread acquires the write 
token, begins flushing its buffer, and then stops without finishing the 
buffer flush and never releases the token. This doesn't happen 
immediately (many commits occur without a problem) but it's happening 
consistently in intruder, kmeans, genome, and ssca2. I have 
XACT_MEMORY=true, XACT_EAGER_CD=false, and XACT_LAZY_VM=true, all set at
 compile time. The benchmarks run fine under eager and we are avoiding 
malloc/other syscalls in transaction. Has anyone seen this before? Or 
have any ideas what might be happening?

Thanks in advance,

Gwen
