Segmentation fault #1

Closed teecrypt closed 6 years ago

teecrypt commented 6 years ago

Thank you for your work on Teechain, it looks very interesting. I downloaded the binary package, but unfortunately it crashes with a segmentation fault.

My system: Linux 4.15.0-36-generic #39~16.04.1-Ubuntu SGX version: 2.1.103.44322

The sample code in SGX SDK works fine. Here are the steps I did with Teechain:

./prepare_sim_mode.sh
./teechain_send.sh

It then fails with segmentation faults as follows:

Starting two ghost teechan enclaves...
Spawning enclave ALICE listening on port 10001 in test_scripts/testnet/test/alice.txt 
./teechain_send.sh: line 34:  2279 Segmentation fault      (core dumped) ./teechan ghost -d -p $ALICE_PORT > $ALICE_LOG 2>&1
Spawning enclave BOB listening on port 10002 in test_scripts/testnet/test/bob.txt 
./teechain_send.sh: line 38:  2282 Segmentation fault      (core dumped) ./teechan ghost -d -p $BOB_PORT > $BOB_LOG 2>&1

When I run it with valgrind, this is the error logged:

Error: Out of memory.
Error something went wrong: initialize_enclave
To prevent fund loss, we are shutting down your enclave, returning your unused deposits, and terminating all your channels. Check your log for the transactions.

Here's valgrind -v dump:

Hi,

Can I check how much system ram you're operating on? An out of memory error seems to suggest the process can't allocate enough memory on enclave initialization. The teechain binaries tend to allocate a lot of memory on startup (several Gigabytes each).

It has 8GB RAM -- I tried increasing the swap size and it went through fine. Thanks a lot!
