When large calls cause errors R may stall for extended periods.? This is particularly likely to happen with `do.call`, as in this example with a 24 second stall: ??? x <- runif(1e7) ??? system.time(do.call(paste0, list(abs, x)))? # intentional error ??? ## Error in (function (..., collapse = NULL)? : ??? ##?? cannot coerce type 'builtin' to vector of type 'character' ??? ##

Luke, thanks for considering the issue.? I would like to try to separate the problem into two parts, as I _think_ your comments address primarily part 2 below: 1. How can we avoid significant and possibly crippling ?? stalls on error with these non-standard calls. 2. What is the best way to view these non-standard calls. I agree that issue 2. requires further thought and discussion under a

We also have a few other suggestions and wishes about backtrace storage and display on the one hand, and display of constructed calls on the other hand. Perhaps it would be better to open a different wishlist item for traceback() to keep the discussions focused? FWIW I think deparsing backtraces lazily is a great idea. Displaying 1 line per call by default in interactive sessions, while being

Hi, In my application I am JITing thousands of functions, though I am doing it sequantially and running only one at a time. So it is crucial to be able to properly clean up the memory from an old JITed function when JITing and running the new one. I am using Haskell binding of LLVM and my application works OK. However, memory usage increases and never decreases during the run time of my

%FIRSTSTRU = type { i32, double, i32, i8* } struct { int var1; double var2; int var3; char *var4; }firstStru ; Could someone help? If, running a application in windows with MSVC, I allocate a memmory buffer and call a LLVM function with such buffer, there's a structure alignment problem. If the LLVM function call a C function using the same buffer, it runs fine. Any ideas?

What cpu/memmory configurations have people had good luck with for a small office asterisk server... (polycom's/poe linksys) Dell's got their $200 SC440 going again until the 12th... and I'm thinking it might be just the ticket...

Hi, Was this ever resolved? I'm curious, I'm also in a situation where there may be many (very many) JITted functions over the history of an application (which may be running for many days) Thanks On Mar 20, 2009, at 7:34 AM, George Giorgidze wrote: > Hi, > > In my application I am JITing thousands of functions, though I am > doing it sequantially and running only

Hello, If an ordinary user runs: -- snip -- cat > starv.c <<EOF main(){ char *point; while(1) { point = ( char * ) malloc(10000); }} EOF cc starv.c while true do ./a.out & done -- snip -- This will fast starv the operating system (FreeBSD 6.2). I have tried to limit the number of processes and the amount of memmory consumed (in login.conf). There is also a file /etc/malloc.conf

Hi! Would like to initialize a huge matrix.csc (Pacakge SparseM) with all elements 0 and afterwards set a few alements nonzero. The matrix which I like to allocate is so huge that I can not use A <- matrix(a,n1,p) before: A.csr <- as.matrix.csc(A) because I can not allocate such a huge matrix A. But I believe that the much more memmory efficient model in case of csc matrix should do it for

Hi, I've been tracking down a memory leak in an rApache application, http://data.vanderbilt.edu/rapache/bbplot. The code was deployed in 2007 and has survived numerous upgrades of both R and rApache (including upgrades and bugs in RMySQL). It's written in such a way so that web crawlers will download every possible URL the app will create. It's not a high-traffic app, but just about

Hi, I'm having high load, choppy sound and slow responsives with an asterisk server (version 1.2.12.1) that make a peak of 90 channels (around 60 phones calling at max, isn't necessary to reach this peak to get the problem). All the traffic is SIP, with recording for every call. The server has: Intel(R) Xeon(TM) CPU 3.20GHz (with HyperThreading disabled for inestability) 4G RAM 2 DD SCSI

Hi all, Just watching for my first time the 'oom-killer' call in a CentOS 4.2 workstation. System was running normally but with high load of nice process, iow, rosetta and seti, others appart, nautilus, etc... i realized that after a night of standby running normally, the next moorning after few manual operations from X-session in local console, it started a massive swapping, this time

Hi all, I am not able to export an ALTREP object when `gctorture` is on in the worker. The package simplemmap can be used to reproduce the problem.

Hi, It's not ok yet. When a C function calls a LLVM function, or a LLVM function calls a C function, the offset of the variables are wrong. When a don't mix LLVM with C, it's ok, but I need call extern functions using structs.

Thanks for the report. Will look into it when I get a chance unless someone else gets there first.
