Playing speed suddenly increases?

I can be quite happily listening to itunes for about an hour then suddenly the playing speed increases rapidly. I have to exit ituens then restart and it works fine again.
I am using itunes 7.3.1.3 with Windows XP Home Edition, Creative SB Audigy 2 ZS sound card and speakers. Never used to have problems until I ran an update one day.
Any ideas how to stop it?
Gary

Have you restored it?

Sudden increase in buffer gets per executions in update statement

Hi,
Recently we have encountered one performance issue, which is most likely caused by a sudden increase in the buffer gets per execution.
The SQL is an update statement, updating a table using a primary key (we have checked to confirm the running execution plan is using the primary key), and one field being updated is a BLOB column.
As shown in the below statistics, there is no major change in the number of executions during the every 20 minutes monitoring interval. However, the buffer gets per executions has been more than double, and the CPU time is almost doubled, hence the exec_time (elapsed time) has been doubled.
The same SQL has been running for the past four years in multiple similar databases. The database is Oracle 9.2.0.4 running on Solaris 9. For the past 300 days, the average elapsed time per execution is about 0.0093s, while the average buffer gets per execution is about 670. The update statement has been executed about 9 times per second.
The question is why there is a sudden increase in the buffer gets? The sudden increase happened twice for the past two days.

I cannot sort my songs using the "plays" column (also known as the number of plays column). The number of "plays" is not increasing as a song finishes.

The "plays" column (also known as the number of plays column) is not saving not saving the number of plays (v 11.0).

My number of 'Plays' was not increasing anymore at some point after updating to Version 11. I had iTunes rev 11.0.1.12. Today I updated to the latest rev 11.0.2.26, and now the numer of plays is increasing, so they must have fixed the bug!

Is there a way to slow down play speed itunes?

Hello. I have recorded some interviews on a pocket voice recording and uploaded them into iTunes on my G5 computer.
In order to transcribe the recordings efficiently, I want to slow down the play speed.
Is there a way to do that?

Sudden increase in Tablespace - Oracle 9.2.0.8

The oracle tablespace increased suddenly but without loading the actual data. On 06/15, the tablespace has a free space on 1.5G, but all of a sudden, all 1.5G has been consumed and casued the batch job to abend due to lack of space in the tablespace. The tablepace was increased by 2.5G and the batch job ws successfully completed. Till now ( after 1 month) there was no decrease in the free space of the tablespace (still 2.5G) and there was a increase in the size of the tablespace.
Please could you help in sudden consumption of the free space by the tabllespace. here are the tablespace storage details.

Hi All,
I got the answer. It is a bug in oracle 9.2.0.8. Oracle support has given as patch to implement and it should resolve issue.Here is the quote from Oracle support " It seems you have hitting the known Bug 5987262 duplicate of Bug 5890312 Unexplained increases in unformatted blocks in a tablespace ..This issue is also addressed by article : Note 469985.1 Ext/Mod Sudden Increase in Unformatted Blocks "
Thanks for your support

Sudden Increase in database size

Hi all,
I have noticed sudden increase in sys schema size, after making queries on DBA_TABLESPCAES, DBA_DATA_FILE,
DBA_EXTENTS,DBA_SEGMENTS.
Does it means Oracle has generated lot of data after queries to these views ?
It's very urgent .
Please reply.

Hi,
Is any application accessing this database? If yes, then did you confirm with the application contact whether any heavy changes have taken place in the application/database? I think that an increase of 300M is not huge but normal/acceptable. However, it is a factor of the actual database size. What is you database size?
Regards.

Sudden increase in BT Infinity Latency - Harwich E...

I have had BT Infinity for a couple of months now and have a SamKnows broadband monitoring unit connected. It originally reported the latency to be 10 milliseconds, however on 9th December at 13:00 it jumped to 20ms and has remained there ever since, so the latency is now worse than it was with my old ADSL2+ (approx 15ms) and my son reports problems with lag now when online gaming.
Does anyone have any idea why the latency should suddenly increase like this, I presume it's a network issue somewhere.
I have a HomeHub 5 fitted.
Whether it's relevant, my connection was the 1st in the cabinet.
Any information would be appreciated. Thanks.
Solved!
Go to Solution.

DLM has probably decided to add interleaving to your line.
If you do a 'tracert bbc.co.uk' you will see the first hop after the HomeHub as around 6ms without interleaving, and around 16 ms with interleaving.
No reason I know of to expect lower pings on FTTC than ADSL. My bbc pings with BE/ADSL were around 11ms (no interleaving) or 20 ms (interleaving). With Infinity they are around 22ms (no interleaving) or 31 ms (interleaved). On BE I had the choice; I chose interleaving for greater stability and lower packet loss depite the ping increase. With FTTC you don't have the choice; you get what DLM gives you. I have been on interleaved for most of my Infinity contract, it was removed a couple of months ago (probably as a result of changes to the updated modem firmware).
A lot of my Infinity extra is the silly routing of all my traffic Winchester->Sheffield->London before it leaves the BT network; this adds around 9ms to my ping times; around 4/5 ms each for the hops north and back south.

Sudden increase in native heap memory

Hi all,
we are using JRockit 26.4 and currently configured with 1800MB heap on windows 2003 with /3GB switch.
We noticed that after the weblogic server is started the total memory (java heap + native memory) lingers around 2550 MB... (We monitored this using perfmon -> virtual bytes of java process)
after couple of days run, the native memory suddenly increased by 300 MB, taking the total virtual bytes to 2850 MB.
Do we know what could be the reason for such a sudden increase?
Thanks,
- Pritam.

I don't believe this is documented anywhere unfortunately, and it might vary depending on the exact JRockit release. But the key thing to watch out for is growth, regardless of which component it is. If you see that, post a question here and we'll find someone to tell you what the issue is...
That said, here's an example printout and some guesses from my side.

---------------------!!!Total mapped means mapped virtual memory, eg the largest size the JVM can be expected to grow to. This is typically on the same order of magnitude as the Java heap size (Xmx).
Total in-use is the actual memory in use, this is the current "memory footprint" of your process.
executable refers to JIT compiled code, I believe.
Java-heap is the heap (duh).
Stacks should be the thread stacks (where local variables are stored).
classes is native memory used to store bytecode etc. If this grows, it may be because you are generating classes dynamically and they are not getting cleaned up because there are still live instances. Or maybe you're running with -Xnoclassgc.
threads can grow if you start a lot of threads and don't let them die.
Stuff under malloc:ed memory is mainly misc JVM metadata.
unaccounted for memory is...everything else. The most common leak involving unaccounted-for is native byte buffers (DirectByteBuffer).

Sudden increase in memory space

We have developed an application using the Hyperion 9.3.1.
We are trying to load data and the data load itself is taking lot of time.
Again, the memory space is getting increased drastically (almost to 100%).
We see lot of page files being generated.
What can be the reason for this sudden increase in memory space utilization.

you should consider the folllowing factors for sudden increase in memory space
1.Minimize the no of hierarchies otherwise it leads to increase in the size of aggregated data and slows down view selection
2. remove fragmentation
3.Compact the outline to remove the records of members that we have been deleted
4.create transparent partition if neccessary which leads to enable write-back partition.By doing this we can reducethe size of the Database and reduces calculation time.
5.use compression if values are grouped together in consecutive members on dimensions or hierarchies rather than spread throughout the outline with lots of
#missing data between values.

Sudden increase in spam on my .me account

Hi,
As the title suggests, Ive had a sudden increase in spam on my .me account.
Its gone from 1 a week to 2 a day, then 5 & now its upto 30 spam a day & there
all from what looks like normal companies ( i know there not though)
Ive even installed spam sieve which works fine but I still have to check it
evey day.
Any suggestions welcome.
Kindest,
Jeff

Forward the spam to [email protected] so Apple can adjust their junk mail filters.

Essbase pag file size had a sudden increase

We have a BSO cube who used to have 1.8g of exported data and about 2.5 gigs of pag files. However, they both suddenly increased to 5 gigs each (in just one day). I checked our logs and there were only a few data uploads/changes and the outline member additions that we had that day were all dynamic calcs members. We do export - clear - reload data everynight, but the exported files and page files are still on th 5 gigs.
Does anyone know what could have caused this issue?
Thank you.

Same type of thing happened here. Overnight, 3 hour agg calc now taking upwards of 8 hours. They had implemented hierarchy additions, nothing drastic.
By chance, were any of these Dynamic Calc members created in sparse dimensions? Do they roll up to stored members? It's bad ju-ju to have that situation.
This was the biggest design offender I found, and am redesigning cube for them right now.
I have taken the 8-10 hour agg (and 41 pag files) down to 36 minutes (and 15 pag files) simply by changing the dense and sparse settings of their cube. One of the dimensions they had dynamic members rolling up to stored members, I made this one dense and made all upper levels dynamic. (of course I had to change some of their other dense dimensions to sparse to accomodate this) But the end results on time and page files tells me that having dynamic calc members roll to stored members is really bad.

Tuning Sudden Increase to Port Traffic

I am looking for suggestions on tuning sudden increase to port traffic for MARS.
We have a third party that we do not want to be actively alerted when they perform their scan. This gives us one set of IP addresses they use to scan.
Next is our internal networks that are the target of those scans. Which gives us a second source.
Unforunately, Mars is reporting these flows as Source 0.0.0.0 Target (Int Host) and Source (Scan Co.) Target 0.0.0.0.
Anyone have any suggestions? I'm worried if I filter by source, I'll loose that portion of the correlation and be left with just the victim IP of the scan, which tells me little.

Have you tried to set that particular session as false positive? (i hope you know that) You can tune the false positive for particular source/destination on per session basis. Once you do that, try and see if it still reports as a scan.

MARS - "Sudden increase of traffic to a port" rule

Hello. I duplicated the system rule "Sudden increase of traffic to a port" in MARS and it blew out the original system rule and now shows up as a user rule. It doesn't appear to be working either. It is active. Not sure what to make of this, and neither is TAC. Anybody every mess up a system rule like this? Anyway to recover it? Thanks!

I upgraded to 4.2.2 and the rule seems to have been restored as a system rule. I noticed that it is showing up in our morning report (Event Types Ranked by Sessions), but we are not recieving an email or page for this rule firing (email/SMS notification works for all other rules). I ran a query for this event for the time period of the report it showed up on and no results were returned. Any thoughts would be appreciated. Thanks.

Sudden increase of AEBS issues? Is it linked to the latest Airport updates?

Is my impression correct that AEBS issues of a certain type (a) have suddendly increased and (b) seem to correlate with the latest Firmware Updates for AEBS?
I posted already a problem (no LAN functionality, I have no access to printers etc). I was wondering what you think about.
Further, does somebody know how I can revert the FW Update 5.7 and go back to 5.6?

"Sudden increase of AEBS issues? Is it linked to the latest Airport updates?"
We are not allowed to ask that question. Remember, it must, must, must be our fault - we have to be careful about that. Well, I guess that if someone who leans to the right politically, can still question the actions of the current president - then I guess it is OK for Mac lovers to question Apple - so I take back what I said at the top.
